Description

Technical Field

[0001] This utility model relates to the technical field of asphalt performance testing equipment, and in particular to an automatic safety tester for asphalt softening point. Background Technology

[0002] As an important building material, asphalt is widely used in road paving, waterproofing projects, and various industrial products. The stability of its performance directly affects the quality and service life of the project. Among the many asphalt performance testing projects, the softening point test is a key indicator for evaluating the high-temperature stability of asphalt, and it is particularly important.

[0003] Traditional methods for testing the softening point of asphalt mainly rely on manual observation, which is cumbersome and the test results are greatly affected by human factors. Although there are now corresponding asphalt softening point testing devices that can provide efficient heating and are easy to operate, they cannot test multiple sets of specimens at the same time, so the efficiency is not high enough.

[0004] Therefore, in view of the above-mentioned traditional asphalt softening point testing methods, which mainly rely on manual observation, the operation is cumbersome, the test results are greatly affected by human factors, and the existing asphalt softening point testing devices cannot simultaneously measure multiple groups of specimens, resulting in low efficiency, an automatic and safe asphalt softening point tester can be designed. This instrument can simultaneously measure multiple groups of asphalt specimens and record the results accurately, ensuring the accuracy of the test results while effectively improving testing efficiency. Utility Model Content

[0005] In order to overcome the problems of traditional asphalt softening point testing methods, which mainly rely on manual observation and are cumbersome to operate and whose test results are greatly affected by human factors, although there are now corresponding asphalt softening point testing devices that can provide efficient heating and are easy to operate, they cannot test multiple sets of specimens at the same time, resulting in insufficient efficiency.

[0006] The technical solution of this utility model is as follows: an automatic safety tester for asphalt softening point, comprising a base, a heating device, a sleeve, a top cover, a mounting rod, a data recording device, an upper circular plate, a lower circular plate, and a sensing device. The heating device is fixedly installed above the base, the sleeve is positioned above the heating device, the top cover is positioned above the sleeve, the mounting rod passes through the top cover, and the mounting rod is fixedly connected to the top cover. A connecting wire is provided inside the mounting rod, one end of which passes through the mounting rod and is electrically connected to the data recording device. The upper and lower circular plates are fixedly installed around the mounting rod, and the lower and upper circular plates are located inside the sleeve. Multiple sets of sensing devices are provided, and the sensing devices are fixedly installed inside the lower circular plate. Multiple sets of connecting wires are provided below the lower circular plate, and the multiple sets of connecting wires are electrically connected to the multiple sets of sensing devices respectively. The connecting wires are electrically connected to the connecting wires.

[0007] Preferably, multiple sets of asphalt specimens can be placed on the upper circular plate, and the sleeve can be supported and placed by the heating device, while the inside of the sleeve is heated. The top cover can be supported by the sleeve, and the mounting rod can be installed by the top cover, so that the upper and lower circular plates around the mounting rod are located inside the sleeve. Thus, the sleeve can surround the upper and lower circular plates inside, which facilitates the heating device below to heat the asphalt specimens on the upper circular plate. The sensing device can be installed on the lower circular plate, and multiple sets of sensing devices can be connected to the data recording device outside the sleeve by the branch line and connecting line. Thus, the data of the softened dripping asphalt sample can be detected by the sensing device, and recorded and displayed by the data recording device. Multiple sets of asphalt samples can be measured simultaneously, which is more efficient.

[0008] Preferably, a display screen is provided on one side of the heating device, and multiple sets of control buttons are fixedly installed on one side of the heating device.

[0009] Preferably, four sets of mounting brackets are fixedly installed above the heating equipment, and a fan is installed above the mounting brackets. The fan is located inside the sleeve, and the four sets of mounting brackets are evenly arranged in a circle around the axis of the sleeve.

[0010] Preferably, a first positioning ring is fixedly installed above the heating device. The first positioning ring is located on the periphery of the sleeve and contacts the outer surface of the sleeve. The sleeve is made of polytetrafluoroethylene (PTFE).

[0011] Preferably, a second positioning ring is fixedly installed below the top cover. The second positioning ring is located inside the sleeve and contacts the inner wall of the sleeve. A heat-insulating sleeve is fitted around the mounting rod and is located above the top cover.

[0012] Preferably, the surface of the upper circular plate is provided with multiple sets of through holes, which are arranged circumferentially around the axis of the mounting rod. The number of through holes is consistent with that of the sensing device and corresponds one-to-one. A metering ring is provided around the through holes, which is located above the upper circular plate and is fixedly connected to the upper circular plate.

[0013] Preferably, a magnet is fixedly installed below the lower circular plate. The magnet has a ring structure, and the sensing device is located inside the magnet. A receiving plate is provided below the magnet, and the receiving plate is magnetically connected to the magnet.

[0014] The beneficial effects of this utility model are:

[0015] During the test, the asphalt samples of different groups to be tested are first cut according to the size of the metering rings. The cut samples are then placed in the metering rings above the upper circular plate, ensuring that each group of samples is the same size and limiting the variables. After the samples are placed, the sleeve is placed above the heating device, and the top cover is placed above the sleeve, so that the upper and lower circular plates are inside the sleeve. Then, the asphalt samples placed on the upper circular plate are allowed to soften. The softened asphalt samples will pass through the through hole and gradually fall to the surface of the sensing device below. The sensing device can collect the test data and transmit the data to the data recording device for recording through the tap line and connecting line. This allows for simultaneous testing of multiple groups of samples, which can effectively improve the testing efficiency while ensuring the accuracy of the test results. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 4This utility model provides an embodiment: an automatic safety tester for asphalt softening point, comprising a base 1, a heating device 2, a sleeve 3, a top cover 4, a mounting rod 5, a data recording device 6, an upper circular plate 7, a lower circular plate 8, and a sensing device 9. The heating device 2 is fixedly installed above the base 1, the sleeve 3 is positioned above the heating device 2, the top cover 4 is positioned above the sleeve 3, the mounting rod 5 passes through the top cover 4, and the mounting rod 5 is fixedly connected to the top cover 4. A connecting wire 501 is provided inside the mounting rod 5, one end of the connecting wire 501 extends out of the mounting rod 5, and the other end of the connecting wire 501 is electrically connected to the data recording device 6. The upper circular plate 7 and the lower circular plate 8 are fixedly installed around the mounting rod 5, and the lower circular plate 8 and the upper circular plate 7 are located inside the sleeve 3. Multiple sets of sensing devices 9 are provided, and the sensing devices 9 are fixedly installed inside the lower circular plate 8. Multiple sets of connecting wires 502 are provided below the lower circular plate 8, and the multiple sets of connecting wires 502 are electrically connected to multiple sets of sensing devices 9 respectively. Electrically connected to connecting line 501; multiple sets of asphalt specimens can be placed by setting the upper circular plate 7; the sleeve 3 can be supported and placed by setting the heating device 2, and the inside of the sleeve 3 can be heated at the same time; the top cover 4 can be supported by setting the sleeve 3; the mounting rod 5 can be installed by setting the top cover 4, so that the upper circular plate 7 and lower circular plate 8 around the mounting rod 5 are located inside the sleeve 3. Thus, the upper circular plate 7 and lower circular plate 8 inside the sleeve 3 can be surrounded, which facilitates the heating device 2 below to heat the asphalt specimen on the upper circular plate 7; the sensing device 9 can be installed by setting the lower circular plate 8; multiple sets of sensing devices 9 can be connected to the data recording device 6 outside the sleeve 3 by setting the tap line 502 and connecting line 501. Thus, the data of the softened dripping asphalt sample can be detected by the sensing device 9, and recorded and displayed by the data recording device 6. Multiple sets of asphalt samples can be measured simultaneously, which is more efficient.

[0023] Please see Figure 1 and Figure 2In this embodiment, a display screen 201 is provided on one side of the heating device 2, and multiple sets of control buttons 202 are fixedly installed on one side of the heating device 2. The heating temperature of the heating device 2 can be adjusted by setting the control buttons 202, which facilitates the control of experimental variables. The heating temperature of the heating device 2 can be displayed by setting the display screen 201, which allows the test personnel to observe the temperature more intuitively. Four sets of mounting brackets 204 are fixedly installed on the top of the heating device 2. A fan 205 is set on the top of the mounting brackets 204. The fan 205 is located inside the sleeve 3. The four sets of mounting brackets 204 are evenly arranged in a circle around the axis of the sleeve 3. The mounting brackets 204 support and install the fan 205. The fan 205 can drive the air flow inside the sleeve 3, thereby making the heat distribution inside the sleeve 3 more uniform. A first positioning ring 203 is fixedly installed on the top of the heating device 2. The first positioning ring 203 is located inside the sleeve. The outer periphery of sleeve 3 is contacted by a first positioning ring 203, which is made of polytetrafluoroethylene (PTFE). The first positioning ring 203 limits and positions the sleeve 3 placed on the heating device 2, preventing accidental movement during the test. The use of PTFE in sleeve 3, compared to traditional glass, effectively avoids the risk of uneven heating and cracking. A second positioning ring 401 is fixedly installed below the top cover 4, located inside the sleeve 3 and in contact with the inner wall of the sleeve 3. A heat-insulating sleeve 503 is fitted around the mounting rod 5, positioned above the top cover 4. The heat-insulating sleeve 503 facilitates movement of the top cover 4 by the test personnel, preventing burns. The second positioning ring 401 positions the top cover 4 when it is placed above the sleeve 3, preventing accidental movement during the test and ensuring the test is conducted correctly.

[0024] Please see Figure 3 and Figure 4In this embodiment, the surface of the upper circular plate 7 has multiple sets of through holes 701. These through holes 701 are arranged circumferentially around the axis of the mounting rod 5. The number of through holes 701 is consistent with and corresponds one-to-one with the sensing device 9. A metering ring 702 is provided around the through holes 701. The metering ring 702 is located above the upper circular plate 7 and is fixedly connected to the upper circular plate 7. By setting the metering ring 702, the placed asphalt sample can be quantified and positioned. By setting the through holes 701, the softened asphalt sample can drip down through the through holes 701. Data is read from the corresponding sensor; a magnet 801 is fixedly installed below the lower circular plate 8. The magnet 801 has a ring structure. The sensing device 9 is located inside the magnet 801. A receiving plate 802 is provided below the magnet 801. The receiving plate 802 is magnetically connected to the magnet 801. By setting the magnet 801, the receiving plate 802 can be fixed below the lower circular plate 8. The receiving plate 802 can also be used to shield and protect the internal sensing device 9. The receiving plate 802 can also be used to receive the softened asphalt left by the lower circular plate 8.

[0025] When working, the asphalt samples of different groups to be tested are first cut according to the size of the metering ring 702, and the multiple groups of cut samples are placed in the metering ring 702 above the upper circular plate 7 to ensure that the size of each group of samples is the same and to limit the variables.

[0026] After the sample is placed, the sleeve 3 is placed above the heating device 2 and positioned using the first positioning ring. The mounting rod 5 is then inserted into the sleeve 3 so that the top cover 4 is placed above the sleeve 3 and positioned using the second positioning ring 401. The heating device 2 is controlled using the control button 202 and set to the stable state of the test plan. The heating device 2 is used to heat the inside of the sleeve 3. At this time, the fan 205 is turned on, which can drive the air flow inside the sleeve 3, thereby making the heat inside the sleeve 3 more uniform.

[0027] Then wait for the asphalt sample placed on the upper circular plate 7 to soften. The softened asphalt sample will pass through the through hole 701 and gradually fall to the surface of the sensing device 9 below. The sensing device 9 can collect test data and transmit the data to the data recording device 6 for recording through the tap line 502 and the connecting line 501, thereby realizing the simultaneous testing of multiple sets of samples. While ensuring the accuracy of the test results, it can effectively improve the test efficiency.

[0028] The receiving plate 802 can be used to receive softened asphalt samples, preventing them from falling onto the heating device 2 below and affecting subsequent tests. At the same time, it can protect the internal tap line 502. The magnet 801 can be used to quickly disassemble and assemble the receiving plate 802, making it easy to clean the receiving plate 802.

[0029] Through the above steps, multiple sets of asphalt specimens can be placed on the upper circular plate 7, and data can be collected from different sets of asphalt samples through multiple sets of sensing devices 9. The data is then recorded by the data recording device 6, ensuring the accuracy of the test results and effectively improving the testing efficiency. This solves the problem that traditional asphalt softening point testing methods mainly rely on manual observation, which is cumbersome to operate and the test results are greatly affected by human factors. Although there are corresponding asphalt softening point testing devices that can provide efficient heating and are easy to operate, they cannot measure multiple sets of specimens at the same time, resulting in insufficient efficiency.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
